Cav Units

Overview:

Circular self-powered volume flow controllers for the control of supply air or extract air in constant air volume systems

Volume flow rate can be set using an external scale, no tools required

High control accuracy

No on-site test measurements required for commissioning

Suitable for airflow velocities of up to 12 m/s

Any installation orientation; maintenance-free

Casing air leakage to EN 1751, class C

Typical Applications

• Circular CONSTANTFLOW CAV controllers of Type 153-253 for the precise supply air or extract air flow control in constant air volume systems
• Mechanical self-powered volume flow control without external power supply
• Simplified project handling with orders based on nominal size
• Volume flow rate setpoint can be set on external scale
• Switching between Vmin and Vmax using optional actuator

Construction Options:

Material

The frame is manufactured from ETIAL-60 Norm aluminium extruded profile. There is a neoprene gasket between the cover and the frame, which can withstand 90ºC. The cover is made of ETIAL-5 norm aluminium sheet. Insulation material is glasswood as per DIN 4102 Class A
